please use XXX ambiguous warning

[tsmgeek]

It seems that there are a few messages about -qscale/-profile/-b etc being ambiguous and use separate audio/video versions? Should the library be updated to correct these issues?

[buggedcom]

Can you post the exact warnings here please, as well as your ffmpeg version number. As there are so many different version of ffmpeg floating out there it's quite hard to keep track of all the messages.

I have checked the latest ffmpeg source on GitHub and they still have the deprecated message there. I am on ffmpeg 2.1, I know that you say you have written to 1.2 but would it not be possible to check early on in the library what version of ffmpeg is being used then switch param as required.

Ive noticed an old pull request https://github.com/buggedcom/phpvideotoolkit-v2/pull/5 asking this to be changed to -qscale from -q, back then really they should have put -q:v

[buggedcom]

When I have some time I will look at doing this based on your suggestion of switching around the version number.

[buggedcom]

I'm creating a new branch called feature/stream-specifiers that will attempt to add in stream specifier functionality.
